Introduction
We all live in a beautiful place called planet earth.
In the beginning there was a balance between the humans and nature.
But as time went by, the human race developed so much that it started to upset the balance, causing serious problems such as global warming, deforestation, pollution and many others.
Global Warming
Global warming is being caused essentially by the emissions of gases such as CO2 and CFC’s.
CO2 is one of the most important greenhouse gasses.
This type of gasses can absorb solar radiations.
Currently the emission of gasses to the atmosphere is rising what causes a stronger greenhouse effect, that causes this issue.
Greenhouse effect
• If we continue this activities the planet will get warmer and warmer and there will be consequences
Consequences
Floods
Consequences
Rise of temperature
Consequences
Acid rain
The list of problems goes on and on and on…
So, what can we do?
What can we do to save our planet?
• Start using renewable energy – Renewable energy is the energy which comes
from natural resources such as sunlight, wind, rain, tides, and geothermal heat.
– They are naturally replenished.
What can we do to save our planet?
• Recycle • Used materials that are transformed, giving
rise to new materials
